The dark olive pigment disappears against any lake bed and is actually very difficult to see when suspended off the rod tips, even in tap clear water.
Regarding knot strength, just like the original Syncro XT, the new Loaded is underrated and the following knot strengths can be achieved using a carefully tied five turn grinner (tested on calibrated digital force meter):
Nominal 10lb (0.30mm) Possible 15lb
Nominal 12lb (0.33mm) Possible 17.5lb
Nominal 15lb (0.37mm) Possible 21lb
Nominal 18lb (0.40mm) Possible 26lb
Although Syncro XT Loaded is limp straight off the spool we recommend soaking it overnight so that it absorbs water and becomes even suppler as it is loaded onto the reel spool.
